Call and Signal provides US amateur-radio learning material. This notice describes information involved in reading the site, following external product links, and emailing the editorial inbox.
Information you send
Messages to [email protected] give us your email address and whatever radio, licensing, or equipment details you include. We use those details to answer the message or review a correction. Please avoid sending private identifiers or emergency information.
Visits and technical records
Nginx, our host, and Cloudflare maintain basic traffic, error, and security records, which may include IP addresses, request times, visited URLs, and browser data. Cookie-free Umami counts page visits and summarizes referrals, devices, and approximate geography. These records support site delivery, abuse prevention, and fault diagnosis and are retained only as operationally needed; no unsupported fixed retention period is promised.
Services and outside links
We do not sell personal data. Service providers handling hosting, security, and aggregate analytics receive the information needed for those functions. Clicking an affiliate link sends you to a separate retailer with its own practices; Amazon Associates and other affiliate relationships may generate a commission for this publication.
Your choices
Email [email protected] to ask about access, correction, or deletion of information you supplied. Some security records may need to remain for legitimate operational reasons. We do not offer visitor accounts, comments, newsletters, on-site forms, or sales checkout.
Contact and updates
Privacy questions can be sent to [email protected]. We will revise this notice when relevant site functions change. Effective date: September 29, 2026.
